A bag of marbles contains 35 blue marbles and 15 green marbles. Which of the following shows the decimal of the fraction of green marbles in the bag?
Answer:
15.35
Step-by-step explanation:
Answer:
0.3
Step-by-step explanation:
We know the bag has 50 marbles total: (35+15=50)Now, put 15 over 50 to make it a fraction: (15/50)Finally, we figure that 15 divided by 50 equals 0.3.Thus, our answer is 0.3!Please answer like this:

Answer:
1) 2^9 = 512
2) 2^(3t) = 2^6 for t=2
Step-by-step explanation:
1) An exponent is used to signify repeated multiplication. Here, the factor 2 is repeated 9 times, so the expression can be written using an exponent as ...
2^9
Using any of a variety of means, the value of this expression can be found to be ...
2^9 = 512
__
2) Assuming the bacteria reproduce by multiplying by some factor in a given time, we can divide the original expression into 3 parts:
(2×2×2) × (2×2×2) × (2×2×2)
If this represents the number after 3 hours, then the number after 2 hours is expected to be ...
(2×2×2) × (2×2×2) = 2^6
That is, there will be (2 h)/(3 h) = 2/3 times as many multiplications by a factor of 2. (2/3)(9) = 6 will be the exponent for the number after 2 hours.

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Step-by-step explanation:
Let the athletes be 3x and 2x.
Now, By the question we get,
(3x-12)/(2x+12) = 5/4
or, 12x-48= 10x+60
or, 2x = 108
so, x = 54
now
3x= 3×54= 162
2x = 2×54=108
The number of athletes were 162 in first team and 108 in second team originally.
x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )
y ----------------------------------------second------------------( y ∈ Nˣ )
The ratio of athletes in the two teams is 3:2
⇒ [tex]\frac{x}{y} =\frac{3}{2}[/tex] (1)
After 12 athletes move from first team to second, the ratio is 5:4
⇒ [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex] (2)
(1),(2) ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]
So: The first team originally has 162 numbers and the second team originally has 108 numbers
ok done. Thank to me :>

Reese has nickels and dimes in his pocket. He counts a total of 11 coins. The total value of his pocket change is 70 cents. Let 'n' represent the number of nickels and let d represent the number of dimes in Reese’s pocket.
Which equations can be used to represent the information in this problem? Check all that apply.
A) 5n + 10d = 11
B) n + d = 11
C) n + d = 70
D) 5n + 10d = 70
E) 10n + 5d = 70
REMEMBER, THIS IS MULTIPLE CHOICE :)
The combine equation that represents the information in this problem is as follows;
n + d = 11
5n + 10d = 70
He has only nickel and dimes in his pocket. The total number of coins is 11 coins. The total cost is 70 cents.
let
n = number of nickels in his pocket
d = number of dimes in his pocket
1 nickel = 5 cents
1 dime = 10 cents
Therefore,
Total number of coins:n + d = 11Total cost of the coins5n + 10d = 70Therefore, the combine equation is as follows:
n + d = 11

What is the perimeter of a rectangle with a length of 15 ft and a width of 32 ft?
A. 47 ft
B. 55 ft
C. 94 ft
D. 480 ft
Answer:
C) 94 ft
Step-by-step explanation:
The perimeter of a rectangle's formula is:
[tex]P = 2l + 2w / P = 2(l+w)[/tex]
I will use the second formula.
We are given the length of 15ft and a width of 32 ft.
[tex]P = 2(15 + 32)\\\rule{150}{0.5}\\P = 2(47)\\\\P = \boxed{94}[/tex]
The answer should be C.
Hope this helps.

Which number line correctly shows –0.8 + 0.6?
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.8 to negative 0.2, and then backwards from 0 to negative 0.8.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to negative 0.8 and then from negative 0.8 to negative 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from 0 to 0.8 and then from 0.8 to 1.4.
A number line going from negative 1.6 to positive 1.6. An arrow goes from negative 0.6 to 0.2 and then from 0 to negative 0.6.
Mark this and return
Answer:
Step-by-step explanation:
Since -0.8 is located to the left of origin so when adding any value it will cause it to shift to the right. For example, add 0.1 to 0.8, we get a value of 0.7 shifting the arrow to the right, same goes for 0.2
-0.8 + 0.1 = -0.7
-0.8 + 0.2 = -0.6
-0.8 + 0.4 = -0.4
-0.8 + 0.6 = -0.2
In this way it ends at -0.2
Step-by-step explanation: I hope this helps:)

The area of a square root is 2.25m2. what is the length of each side of the square?
Show work pls, thank you.
Answer:
1.5 m
Step-by-step explanation:
Area = length * width
or we can say
Area = side1*side2
since they are the same we can say
Area = side * side
which also means area = side^2
so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting
so
sqrt(Area) = side
so
side = sqrt(2.25)
= 1.5 m

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50
➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1
